没有找到任何相关信息。 问题是: 是否可以将变量添加到json文件,然后以下列方式使用它
json文件:
{
"s1": {
"text": "Benefit from falling {{ symbol }} prices as well as rising {{ symbol }} prices. Buy or sell instantly"
}
}
位指示:
$scope.symbol = 'gold';
查看:
<p>{{content.s1.title}}</>
我想得到的是:
受益于金价下跌以及金价上涨。立即买入或卖出
感谢您的帮助

您应该使用$interpolate
:
HTML:
angular.module('app', []).
controller('ctrl', function($scope, $interpolate) {
$scope.content = {
"s1": {
"text": "Benefit from falling {{ symbol }} prices as well as rising {{ symbol }} prices. Buy or sell instantly"
}
};
$scope.symbol = 'this is a test';
$scope.resolveText = function(t) {
return $interpolate(t)($scope);
};
});
JS:
resolveText
P.S。 {{1}}可以快速向您展示其工作原理。我认为创建一个封装逻辑的指令会更好。

您可以使用String.prototype.replace
假设mystr
是您的JSON内容的示例。
$scope.symbol = 'gold';
mystr.replace('<symbol>', $scope.symbol);
返回
{
"s1": {
"text": "Benefit from falling gold prices as well as rising gold prices. Buy or sell instantly"
}
}
用法:string.replace(substr|regex, newSubstr|function)

var result = $interpolate("Some string with {{var}}")({var: "Value"});
